SLRGear Tested the 40XS Lens

Seems to be fairly good enough on APS-C for those things that are measured. And their results resemble my practical experiences.

But still, there are many things that they cannot check with their tests, one thing is about the colour rendition. IMO, the image colours produced by the 40XS lens are somehow lowly-saturated. And, the other unmeasured IQ aspects are all inferior to my old FA43 Limited too, frankly. The differences can be easily seen once the lenses are used in the field for instance, not even a side-by-side test is really necessary to tell the truth.
